SUMMARY : GOLDEN RICEOne of the applications of recombinant DNA technology in enriched foods field is golden rice. The organism used is daffodil or maize, bacteria Erwinia uredovora and Escherichia coli. The insertion of phytoene synthase (psy) gene from daffodil or maize and phytoene desaturase (crt I) from Erwinia uredovora into rice genome reintroduced carotenoid biosynthetic pathway in the endosperm that was absent before. This gives the ability of making β-carotene (precursor of Vitamin A) in the endosperm instead of vegetative tissue of rice plants. The phosphomannose isomerase (Pmi) gene from E. coli helps in positive selection of intended genes for producing golden rice [1]. The recombinant DNA product is golden rice. The first generation of golden rice obtained by introducing foreign psy gene of daffodil and crt I gene of bacterium Erwinia uredovora into wild type rice strain genome. This produced 6 μg/g of carotenoids that correspond to1.6 μg/g of β-carotene [1]. The successor GR2 is obtained by replacing psy gene from daffodil with similar gene from maize, produced total carotenoid up to two fold (maximum 37 μg/g) that correspond to 31 μg/g of β-carotene [2]. Rather than spotting white colour as ordinary rice, golden rice is yellow dependent on the quantity of accumulated β-carotene inside grains which is absent in wild type rice strain [4]. The application of this product is to provide adequate vitamin A according to recommended daily allowance (RDA) in rice-based developing countries that being plague with vitamin A deficiency (VAD) issue. Lack in daily supplementation of vitamin A weakened immune system of million infant and children, caused death while left thousands blind. The death rate for women during or shortly after pregnancy also suffered from VAD [3]. The countries affected by VAD especially in Southeast Asia relied on rice as their basic staple. Thus supplementation of Vitamin A through rice is potentially effective when other source...

...GoldenRice is rice that has been genetically engineered to contain beta-carotene and other carotenoids in the endosperm, the edible part of the grain. When you eat the rice, some carotenoids are converted in the body into vitamin A. Goldenrice was developed to be used in areas where there is a shortage of dietary vitamin A. People living on a poor diet are at risk of becoming vitamin A deficient, which can...

Vitamin A is one of the most important vitamins to humans, and it plays an inevitable role in our daily life, thus Vitamin A deficiency (VAD) affects millions of people, causing serious health problems. Therefore, scientists are searching for the most effective method to let people obtain enough Vitamin A as possible. As a consequence, the scientific program of cultivating GoldenRice has attracted people’s attention....

Genetically modified GoldenRice (GR) is a form of rice grain known as Oryza sativa, which has been genetically engineered to contain a pursued quantity of vitamin A. Uncooked GR has an attractive yellow to orange colour, which fades after cooking due to the loss of translucency of the starch in the grain. GR contains high amounts of beta-carotene (β-carotene) in the endosperm, although it is...

...vitamin A, are a major cause of mortality impoverished countries. A new movement, called the GoldenRice Project, is working to provide these impoverished countries the vitamins and nutrients they need. The "GoldenRice" is a case of biofortification where rice plants are genetically modified to produce and accumulate vitamin A in their grains, a trait not found in nature. In this paper, I will use The Golden...

Vitamin A deficiency is one the most common nutritional deficiencies in developing regions. Deficiency in vitamin A can negatively affect growth, cause blindness, and suppress the immune system. To solve this problem green leafy vegetables and yellow fruits and certain animal produces B carotene are used to synthesize vitamin A. This can be done by direct manipulation of an organism's genome using biotechnology; first...

...to get, rice at a one time in the world was the a hot commodity. Rice is a tall grass that grows in a variety of conditions although it flourishes in wet, warm tropical climates. Rice is a food of the Old World. People who lived close to the River rivers started growing rice first in continents like Africa, India, South America and Asia. Citizens of these nations learned how to grow rice in the wet and warm conditions of...

...Rice growing in Mekong Delta has an ancient history traced to the Khmer regime of the 18th century. It was taken over by the Vietnamese. However, the Cambodians still consider this area as "KamPuchea Krom or Lower Cambodia" not able to forget that they owned this area in the past. Cambodia even attacked Vietnam in 1978 to take control of the Mekong Delta. However, they were decisively defeated.[2] This delta was the last part of the present day Vietnam that was annexed from...

Antonio, a Venetian merchant, complains to his friends, Salarino and Solanio, that a sadness has overtaken him and dulled his faculties, although he is at a loss to explain why. Salarino and Solanio suggest that his sadness must be due to his commercial investments, for Antonio has dispatched several trade ships to various ports. Salarino says it is impossible for Antonio not to feel sad at the thought of the perilous ocean sinking his entire investment,...
